NEGATIVE-ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS SECONDARY BATTERY AND NON-AQUEOUS SECONDARY BATTERY

NEGATIVE-ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS SECONDARY BATTERY AND NON-AQUEOUS SECONDARY BATTERY

A negative-electrode active material comprises a graphite including boron and nitrogen. A ratio R1 satisfies 0.5≤R1≤1, where R1=SBN/SB, and SB denotes a total peak area of a boron 1s spectrum of the graphite obtained by X-ray photoelectron spectroscopy, and SBN denotes a peak area of a spectrum assi...

description A negative-electrode active material comprises a graphite including boron and nitrogen. A ratio R1 satisfies 0.5≤R1≤1, where R1=SBN/SB, and SB denotes a total peak area of a boron 1s spectrum of the graphite obtained by X-ray photoelectron spectroscopy, and SBN denotes a peak area of a spectrum assigned to boron bonded to nitrogen in the boron 1s spectrum. A ratio R2 satisfies 0
